Li Shizhen's Compendium of Materia Medica and Tang Shenwei's Reconstruction of Documentary Materia Medica in Song Dynasty both recorded the geographical environment of six kinds of Ganoderma lucidum in detail. There is a saying that "Chi Zhi gives birth to Huoshan, Qing Zhi gives birth to Mount Tai, Huang Zhi gives birth to Songshan, Bai Zhi gives birth to Huashan, Black Zhi gives birth to Changshan, and Zi Zhi gives birth to high mountains and summer valleys".

Therefore, Huoshan County is the birthplace of Chizhi referred to by ancient Li Shizhen.
